You may think painting is just choosing a color and picking the brush. But what you may not know is why the best painting contractors Markham are the best. Their secret is behind the scenes prep.

Prep is not just scraping and sanding; it's fixing flaws, sealing edges, and crafting a flawless base.

That’s why their work lasts. And why yours might not.

According to the best painting contractors Markham, up to 80% of paint failures occur because the surface wasn’t properly prepared. Keeping this in mind, you should change how you approach every paint job.

A General Review

• 80% of paint failures are caused by poor prep

• 70% of the total project time is prep, not painting

• 10+ years, a properly prepped job can last

Why prep matters more than paint

Paint needs a clean surface to stick to. It bonds to whatever is underneath. If the surface is dirty, wet, shiny, or damaged, the paint won’t last. It may look fine at first, but cracks will show up after a few months.

Think of it like putting tape on a dusty shelf. At first, it sticks, but soon it falls off because it was only attached to the dust, not the shelf.

The same thing happens if painters skip prep and start painting right away. The paint sticks to whatever is on the surface, like grease, chalk, or old paint. When that layer fails, the new paint peels off too.

Even the best paint won’t last on a poorly prepared wall. On the other hand, mid-grade paint can last much longer if the prep is done right. This always holds true.

Proper prep actually involves

1

The surface should be well cleaned. A quick wipe isn’t enough. You need to remove grease and dirt. Over time, walls accumulate cooking oil, dust, and grime, which prevent paint from sticking. Be extra careful in kitchens and bathrooms.

2

Fix any damage. Fill and sand every nail hole, crack, and dent until they’re even with the wall. If you rush, repairs will show through the new paint. Let each layer dry fully before moving on.

3

Sand the surface to remove any shine so the paint can stick. Sanding also smooths repairs and removes loose, old paint. If you can feel a repair with your hand, it will show through the final coat.

4

Use primer. Not all primer is cheap paint. Primer works on different problems. The stain-blocking primers cover marks from water and smoke stains. Adhesion primers help paint stick to difficult surfaces. Failing to use primer is a mistake many painters make.

5

Check for moisture. If paint is peeling or bubbling, there’s moisture behind it. Painting over it only hides the problem. The paint will fail again, often worse than before.

A good rule is that prep work should take about twice as long as painting. If a contractor starts painting in the first hour, they probably skipped the prep.

The mistakes that kill a paint job

• Painting over a surface that hasn't been properly cleaned. Grease and dust are invisible barriers that break the bond.

• Using the wrong filler for the job. Lightweight spackle on large repairs and cracks. Setting a compound where it isn't needed creates problems.

• Painting over glossy old paint without sanding or a bonding primer. New paint won't stick to a slick surface.

• Skipping primer to save time or money. This almost always results in having to repaint sooner.

• Painting in the wrong conditions. Below 10°C or above 30°C, water-based paints don't cure properly.

• Painting over moisture problems without fixing the source. The paint will bubble and peel again within months.

How to tell if a contractor is doing the prep right

Most homeowners don’t notice good or bad prep until the paint fails. Here are some signs to check before you approve any job.

They spend time looking before they start

A professional will first have a survey of the space. They look out for problem areas, check for moisture damage, and explain what needs fixing. They won't give a quote without looking around, and if they do, that’s a warning sign.

You see sanding before you see a brush

You should see dust, tape, drop cloths, and products like cleaners, primers, and repair compounds. If the area looks untouched before painting starts, the prep was skipped.

They don't rush the timeline

Good prep is time-consuming. Spackle needs to be cured, and primer needs to be dried. If your contractor finishes in half the time quoted, they skipped steps, not worked faster.

They can explain their primer choice

Ask painting contractors Markham, for which primer they use and why. A professional will answer confidently. If they seem unsure or give a vague answer, they are probably using the cheapest option.

Ask to see a job they finished four or five years ago. The current condition will show you how well they did the prep work.

What a properly prepped job by the best painting contractors Markham looks like long-term

Interior paint on a well-prepped surface can last seven to ten years in most rooms. Exterior paint lasts 5 to 10 years, depending on the material and weather. If prep is rushed, these numbers drop sharply.

A paint job without proper prep might look good for six months. Then corners start to lift, repairs show through, and water stains appear. You will have to repaint, but first, you will need to remove the failed paint.

It always costs more to redo a paint job than to do it right the first time.

What does this mean when hiring in Markham

When comparing quotes from painting contractors Markham, the lowest price is rarely the best value. A low quote often means less time spent on prep, leading to a job that lasts less time.

Ask for a quote that separates prep work from painting. A professional should tell you exactly how many days are planned for each. If prep is not listed as a separate item, ask for more details.

Homeowners trust the best painting contractors Markham for lasting results. They never cut corners on prep to win a job. They take the time to do the work that makes your paint job last.
